TAKE-UP MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 769,580, datedSeptember 6, 1904.

Application file December '7, 1903. Serial No. 184,181. (No model.)

To all 1071/0711, it nmy (ID/b08777 Be it known that I, GUSTAVE E.ANDERSON, a citizen of the United States, residing in Philadelphia,Pennsylvania, have invented certain Improvements in Take-Up Mechanismfor Looms, of which the following is a specification.

The object of my invention is to so construct take-up mechanism forlooms that any desired change in the speed of take-up, and consequentlyany desired change in the number of picks of weft-thread in an inch ofwoven fabric, can be effected by change of one of the spnr-wheels in thetrain of gears whereby movement is transmitted from the ratchet wheelforming the primary member of said train to the wheel on the shaft ofthe take-up roll, the wheels of the train being such that the number ofteeth in the change gear-wheel will represent the desired number ofpicks to the inch.

In the accompanying drawings, Figure I is a side view of suflicient of aloom to illustrate my invention; and Fig. 2 is a view of the same.partly in end elevation and partly in section.

1 represents part of one of the side frames of the loom, and 2 part ofthe swinging lay, which carries a pin 3, engaging with a slotted lever4, the latterbeing hung to a pin 5, which is adjustable longitudinallyin a slotted lug 6 on one of the bars of the frame 1. In addition to theslot 7, which engages the pin 3, the lever A has a slot 8 for thereception of a pin 9, which is adjustable in said slot 8 from and towardthe fulcrum-pin 5 of the lever, and said pin 9 carries a pawl 10, whichengages with the teeth of a ratchet-wheel 11, the latter being mountedso as to be free to turn upon a stud 12, which is secured to andprojects from a slide 13 on the side frame 1 of the loom. Verticaladjustment of this slide 13 on the loom-frame is in the present instanceeffected by providing said frame with a vertical slot 14 for thereception of the bolt 15, whereby the slide is secured to the frame, alug 16 on the slide also entering said slot, as shown in Fig. 2, so asto insure the proper guidance of the slide in its vertical movement.

I-Iung to the fulcrum-pin 5 of the lever A is a detent 17, which engageswith the teeth of the ratchet-wheel 11 and prevents back movement of thesame. Secured to the hub of the ratchet-wheel 11 is a pinion 1S, andmeshing with the latter is another pinion, 19, which is free to turnupon a stud 20, secured to and projecting from the slide 13, said pinion19 meshing with a spur-wheel 21, which is secured to a shaft 22 free toturn in a hanger 23, secured to the frame 1, as shown in Fig. 2, saidshaft 22- also having a spur-pinion 24:, which meshes with a spur-wheel25 on the shaft of the take-up roll 26.

The spur-wheel 21 constitutes the changewheel of the gearing and has asmany teeth as the desired number of picks per inch in the fabric to bewoven. The ratio of the spurwhcel 25 and pinion 2%. being fixed and thenumber of teeth in the ratchet-wheel being also known, all that remainsto be determined in order to permit of the use of a changewheel of thecharacter described is the relation of the circumference of the take-uproll' 26 to the number of teeth in the pinion 18, the pinion 19 being anegligible quantity, since it is employed simply for causing the properdirection of rotation of the take-up roll and has no effect upon thespeed of movement of the same. Assuming that G represents thecircumference of the take-up roll, P the number of teeth in the pinion18, R IN the number of teeth in the ratchet-wheel, and R the ratiobetween the wheels 2% and 25, the

same number of teeth as the number of picks per inch in the fabric whichis being woven, substantially as specified.
